Good plugin, but I can't get PurePerms to work with it? Anybody know how? Also, it comes up with this error sometimes:

[Server thread/CRITICAL]: Unhandled exception executing command 'rankup' in rankup: Argument 1 passed to _64FF00\PurePerms\ppdata\PPUser::setGroup() must be an instance of _64FF00\PurePerms\ppdata\PPGroup, null given, called in phar:///storage/emulated/0/PocketMine/plugins/plugin-830.phar/src/rankup/permission/PurePerms.php on line 10 and defined

Its good but I didnt think that using 'say' was very savy. so i edited the groups.yml file to use xsudo like so : "xsudo {name} me Ranked Up..." You should use this file in the next update and automatically install xSudo when you load the plugin. heres the link to the new file https://www.mediafire.com/?y8a6dcck88dallu

Also to make prisons servers complete you should consider making a plugin where people can buy cells :)
